Appearance of WGF™

Anti-reflection effect with WGF™

Processed parts with WGF and another materials

  • Reflective polarization film with low heat absorption
    Usable in both transmission and reflection use
  • Low AOI dependence
    Stable optical performance even at wide AOI such as PBS
  • Wide effective range from VIS to IR or more
    The anti-reflection effect when using with IR image sensors has been used in several industrial fields.
  • Excellent reliability in high temperature and humidity conditions
    WGF™ can be used even in an environment where conventional polarizer cannot be used. Popular in automotive use or high brightness lighting.
  • Flexible and excellent processability
    Several kinds of processing such as cutting into complicated shapes, bonding to other materials, and curved surface molding are possible. We can offer you it as a processed product.

  • Like HT11N and HT11U, even if adhesive is attached to substrate, the optical performance is not affected.
  • Like HC12A, if adhesive is attached to the wire grid (WG) layer, the optical performance will degrade. On the other hand, the WG surface is protected, making it easier to handle.
  • The COP substrate has a high flatness and is effective for reflective use. COP has low adhesiveness, and surface treatment may be required to firmly bond.

How to cut WGF™

How to cut WGF™
Die-cutting
The most common cutting method. Can process complicated shapes.
Laser-cutting
Can cut even WGF™ laminated on a thick material.

Lamination on other materials

Lamination on other materials
Glass/PC/PMMA
For reflective applications, it is laminated with highly flat glass. PMMA and PC are also common.
Absorptive polarizer
Effective when you want to remove reflection performance in consideration of stray light.

More complicated processing

More complicated processing
PBS (Polarizing Beam Splitter)
An optical component with WGF™ sandwiched between prisms. Widely used in AR-glass using LCOS.
Attachment with frame
WGFTM laminated on glass with a metal frame. It can be attached to a sensor as it is.
3D-formed product
Parts that are combined with other resins and molded into a 3D shape like a lens. Under development for next-generation VR.
